I simple don't think it can be relied upon by it's self to understand God I think you also need to try to follow all the commandments and establish a relationship with God in order to fully understand what God wants from you. There are also times when we can't begin to understand God as we only know what he would want us to know.
Who said it could?
Doesn't change the fact that people will kill you?
Which is not a contradiction in the Bible.
If you want to talk about a subject you should know it well enough not to need Google. Until you reach the point that you can talk about the Bible without needing help you should not try to talk about the contradictions in the Bible, especially when you are actually talking about the differences between what people are doing and what you believe the Bible teaches.
Why do you think that? Just because people believe that now does not mean they believed it 2000 years ago.
You should also be aware that the church fathers did not write the New Testament, the apostles did. The church fathers were the second and third generation of the disciples, many of them studied under the various apostles.
I do not know what you believe exactly so I cannot tell you which denomination believes what you do. I can tell you that there are denominations that teach that the trinity is false doctrine, the most notable of them being Jehovah's Witnesses.
That makes you crazy by most definitions.
Most of the contradictions are actually between the two historical tracks of the Old Testament.
Your probably a theologian I am just an Art Student. You tell me where the contradictions are I am sure you know their there. Wasn't there some thing about needing to be circumcised in the old testament and then in the new testament they claim it's okay to not be?
Circumcision is a sign of the covenant between Abraham and his descendents and God. That covenant is not the same one Christians operate under. That is not a contradiction.
